Description

Technical Field

[0001] This invention relates to the field of inverter support technology, specifically to an inverter support device. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) energy (from batteries or storage batteries) into alternating current (AC) energy (typically 220V, 50Hz sine wave) with fixed frequency and voltage or variable frequency and voltage. It consists of an inverter bridge, control logic, and filter circuits, and is widely used in air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. In foreign countries, due to the high rate of car ownership, inverters can be connected to batteries to power electrical appliances and various tools when working or traveling. Car inverters that output through the cigarette lighter socket have power specifications ranging from 20W, 40W, 80W, 120W to 150W. Higher power inverters need to be connected to the battery via connecting cables.

[0003] Currently, when installing inverters on the roof, a support frame is typically installed first. The bottom of the support frame has multiple clamping blocks, which are then fixed with screws and bolts. The inverter is then installed on the support frame. During the installation of the support frame, screws and bolts are also needed to fix the entire support frame to the roof. However, during the tightening of the screws, the support frame is not only prone to shaking and damage, but the entire installation process is also time-consuming and labor-intensive. Therefore, we propose an inverter support device. Summary of the Invention

[0004] The purpose of this invention is to provide an inverter support device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an inverter support device, comprising a frame, wherein multiple sets of limiting grooves are formed on the crossbars at the lowest end of the frame, and multiple sets of stabilizing shafts are fixedly connected to the bottom end of the frame; further comprising an installation assembly, wherein the installation assembly includes a fixed frame disposed on the frame and fixedly connected to its top end, multiple sets of insertion grooves are formed on both sides of the fixed frame, and a support rod fixedly connected to the frame is fixedly connected to the bottom end of the fixed frame, wherein a movable seat located in the fixed frame is slidably connected to the support rod near its top end, and inclined surfaces are provided on both sides of the bottom end of the movable seat; the installation assembly is disposed on the frame and located at the center; and an insertion assembly, wherein the insertion assembly includes a support rod disposed on the support rod and a fixedly connected support rod is fixedly connected to the frame. A rectangular frame is slidably connected to the fixed frame and located below the movable seat. The plug-in assembly is disposed on the frame and cooperates with the installation assembly. A clamping assembly includes two sets of push rods respectively disposed at the bottom end of the rectangular frame. The two sets of push rods are arranged in a figure-eight shape, and one end of each is rotatably connected to the bottom end of the rectangular frame. The clamping assembly is disposed near the bottom end of the frame and connected to the plug-in assembly. This solves the problem that in the original installation process of the support frame, screws and bolts were needed to fix the entire support frame to the roof. However, during the tightening of the screws, the support frame was not only prone to shaking and damage, but the overall installation process was also time-consuming and laborious.

[0006] Preferably, the mounting assembly includes two sets of mating plates respectively disposed on both sides of the fixing frame. Multiple sets of plug-in blocks adapted to the plug-in slots are fixedly connected to the mating plates. Each plug-in block has an inclined surface adapted to the inclined surface of the movable seat. Multiple sets of tension springs fixedly connected to the fixing frame are also fixedly connected to the mating plates. A sliding sleeve slidably connected to the support rod is fixedly connected below the movable seat. The mounting assembly also includes a placement mechanism disposed on the movable seat, and a limiting mechanism disposed at the top of the fixing frame and connected to the two sets of mating plates. This design allows the multiple sets of inclined blocks to provide a buffering effect during the downward movement of the movable seat, and facilitates fixation to the current installation position after movement.

[0007] Preferably, the limiting mechanism includes a bolt disposed on and rotatably connected to any one set of the mating plates, and a nut adapted to the bolt fixedly connected to another set of the mating plates. An operating block is fixedly connected to the end of the bolt away from the nut, and the bolt passes through the fixing frame. A first rack is fixedly connected to both sets of the mating plates, and a first gear rotatably connected to the frame is disposed between the two sets of first racks. The first gear is meshed with both sets of racks. The limiting mechanism ensures that the movement of the two sets of mating plates is always synchronized and cannot be moved arbitrarily after installation.

[0008] Preferably, the placement mechanism includes a connecting shaft disposed on and fixedly connected to the movable seat, a base frame fixedly connected to the connecting shaft, a sliding frame adapted to the base frame slidably connected to the base frame, a through groove at the bottom end of the base frame, and an operating groove on the sliding frame, which is beneficial for the installation of the inverter.

[0009] Preferably, the plug-in assembly includes a first spring disposed between the fixed frame and the rectangular frame, the first spring being sleeved on the support rod, a lifting plate that is slidably connected to the bottom end of the rectangular frame, and multiple sets of plug-in plates that are fixedly connected to both ends of the lifting plate. The plug-in assembly also includes a docking mechanism disposed in the limiting groove and adapted to the plug-in plates, so that after the installation assembly is operated, the plug-in assembly can be adjusted accordingly, which is beneficial for the initial installation of the frame.

[0010] Preferably, the docking mechanism includes an inclined block disposed in and slidably connected to the limiting groove. The inclined block is adapted to the plug-in plate, and multiple sets of the inclined blocks on the same side are arranged in a mirror image. A matching first clamping block is fixedly connected to the bottom end of the inclined block. A second spring is disposed in the limiting groove, one end of which is fixedly connected to the frame. The other end of the second spring is fixedly connected to the inclined block. The docking mechanism makes the initial installation of the frame easier to control.

[0011] Preferably, the clamping assembly includes two sets of sliding plates mirror-mounted at the bottom of the frame and slidably connected thereto. The sliding plates are rotatably connected to the bottom of the push rod. A second clamping block is fixedly connected to both ends of the sliding plates. Sleeve plates are slidably connected to the four corners of the bottom of the frame. A third clamping block adapted to the second clamping block is fixedly connected to each sleeve plate. The clamping assembly also includes a mating mechanism mounted on the frame and connected to the sliding plates and sleeve plates, so that the frame can be finally installed and the overall stability can be improved.

[0012] Preferably, the mating mechanism includes a second gear disposed at the four corners of the bottom end of the frame and rotatably connected thereto, a second rack that meshes with the second gear is fixedly connected to both ends of the sliding plate, and a third rack that meshes with the second gear is fixedly connected inside the sleeve plate, so that the second clamping block and the third clamping block can quickly engage.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention effectively solves the problem that in the original installation process of the support frame, screws and bolts were needed to fix the entire support frame to the roof. However, during the tightening of the screws, the support frame was not only prone to shaking and damage, but the overall installation process was also time-consuming and labor-intensive. By setting up the installation components, the multiple sets of inclined blocks have a buffering effect when the moving base moves downwards, and it is easy to fix it in the current installation position after the movement. The setting of the limiting mechanism ensures that the movement of the two sets of mating plates always keeps them synchronized and cannot be moved arbitrarily after installation. The setting of the placement mechanism is beneficial to the installation of the inverter.

[0015] 2. The present invention incorporates a plug-in assembly, which allows for corresponding adjustments after the installation assembly is operated. This facilitates the initial installation of the frame and fixes the installation position. The docking mechanism makes the initial installation of the frame easier to control, while the clamping assembly ensures the final installation of the frame and improves overall stability. Furthermore, the cooperating mechanism allows the second and third clamping blocks to quickly engage. Attached Figure Description

Furthermore, mounting assembly 4 includes a limiting mechanism 18 disposed at the top of the fixing frame 5 and connected to the two sets of mating plates 13. The limiting mechanism 18 includes bolts disposed on any set of mating plates 13 and rotatably connected to them. 19. On another set of mating plates 13, a nut 20 that matches the bolt 19 is fixedly connected. An operating block 21 is fixedly connected to the end of the bolt 19 away from the nut 20, and the bolt 19 passes through the fixing frame 5. A first rack 23 is fixedly connected to both sets of mating plates 13. A first gear 24 that is rotatably connected to the frame 1 is provided between the two sets of first racks 23. The first gear 24 is meshed with both sets of racks. The placement mechanism 17 includes a connecting shaft 25 that is set on the movable seat 8 and fixedly connected to it. A base frame 26 is fixedly connected to the connecting shaft 25. A sliding frame 27 that matches it is slidably connected to the base frame 26. A through groove is opened at the bottom of the base frame 26. An operating groove is opened on the sliding frame 27.

[0032] The plug-in assembly 9 includes a first spring 28 disposed between the fixed frame 5 and the rectangular frame 10. The first spring 28 is sleeved on the support rod 7. The bottom end of the rectangular frame 10 is fixedly connected to a lifting plate 29 that is slidably connected to the support rod 7. Both ends of the lifting plate 29 are fixedly connected to multiple sets of plug-in plates 30. The plug-in assembly 9 also includes a docking mechanism 31 disposed in the limiting groove 2 and adapted to the plug-in plates 30. The docking mechanism 31 includes an inclined block 32 disposed in the limiting groove 2 and slidably connected to it. The inclined block 32 is adapted to the plug-in plates 30, and multiple sets of inclined blocks 32 on the same side are arranged in a mirror image. The bottom end of the inclined block 32 is fixedly connected to a corresponding first clamping block 33. A second spring 34 is disposed in the limiting groove 2 with one end fixedly connected to the frame 1, and the other end of the second spring 34 is fixedly connected to the inclined block 32.

[0033] The clamping assembly 11 includes two sets of sliding plates 35 mirror-mounted at the bottom of the frame 1 and slidably connected thereto. The sliding plates 35 are rotatably connected to the bottom of the push rod 12. A second clamping block 36 is fixedly connected to both ends of the sliding plates 35. A sleeve plate 37 is slidably connected to the four corners of the bottom of the frame 1. A third clamping block 38 adapted to the second clamping block 36 is fixedly connected to each sleeve plate 37. The clamping assembly 11 also includes a mating mechanism 39 mounted on the frame 1 and connected to the sliding plates 35 and the sleeve plates 37. The mating mechanism 39 includes a second gear 40 mounted at the four corners of the bottom of the frame 1 and rotatably connected thereto. A second rack 41 meshing with the second gear 40 is fixedly connected to both ends of the sliding plates 35. A third rack 42 meshing with the second gear 40 is fixedly connected inside the sleeve plate 37.

[0034] To improve overall installation efficiency, the frame 1 is first moved to the installation location, and the two sets of first clamping blocks 33 are positioned at the top connection points of the roof corrugated steel tiles. Then, the base frame 26 is pushed downwards. The base frame 26, through the connecting shaft 25 fixedly connected to it, drives the movable seat 8 to move downwards simultaneously. The movable seat 8 further drives the sliding sleeve 16 fixedly connected at the bottom to slide on the support rod 7. The movable seat 8 slides through the inclined surfaces on both sides of the bottom end with the inclined surfaces of the two side insertion blocks 14. The multiple sets of insertion blocks 14 on both sides are sequentially pressed by the movable seat 8, and the insertion blocks 14 slide accordingly in the insertion groove 6, thereby driving the mating plate 13 fixedly connected to it to move in the opposite direction. The tension spring 15 between the fixed frame 5 and the mating plate 13 engages in tension, and the mating plate 13... When the mating plate 13 moves, it simultaneously drives the first rack 23 at the top to move. The first gear 24 meshing between the two sets of first racks 23 ensures that the movement of the two sets of mating plates 13 is consistent. When the moving seat 8 moves to the bottom of the fixed frame 5, the operating block 21 is grasped and rotated. The operating block 21 then drives the bolt 19 fixedly connected to it to rotate. Through the threaded connection between the bolt 19 and the nut 20, the bolt 19 and the nut 20 are connected, thus fixing the position of the two sets of mating plates 13 and preventing them from moving at will. After the moving seat 8 is fixed, the sliding frame 27 is first pushed to one side on the base frame 26, and then the inverter is placed on the base frame 26. After placement, the sliding frame 27 is pushed back to its original position, so that the inverter is fixed between the base frame 26 and the sliding frame 27.

[0035] When the movable seat 8 moves the sliding sleeve 16 downwards, the bottom end of the sliding sleeve 16 first contacts the top end of the rectangular frame 10. As it continues to move downwards, it pushes the rectangular frame 10. After being pushed, the rectangular frame 10 slides downwards and compresses the first spring 28. As the rectangular frame 10 slides downwards, it also drives the lifting plate 29, which is fixedly connected to the bottom end, to descend simultaneously. The lifting plate 29 has four sets of plug-in plates 30 at both ends. After the plug-in plates 30 follow the lifting plate 29 downwards, they contact the inclined block 32 and gradually compress the inclined block 32. The slide is made in the limiting groove 2 and the second spring 34 is squeezed. When the position of the moving seat 8 is fixed, the bottom end of the plug plate 30 is fully inserted into the limiting groove 2. The two sets of corresponding inclined blocks 32 are squeezed at the same time, and the first clamping block 33 fixedly connected to the bottom end of the two sets of inclined blocks 32 cooperates at the same time to clamp the roof at the installation location and initially fix the frame 1 as a whole. When the frame 1 is placed on the roof, the stabilizing shaft 3 at the bottom end of the frame 1 is used for fixation, while the bottom height of the first clamping block 33, the second clamping block 36 and the third clamping block 38 is higher than the stabilizing shaft 3 at this time, and they are in a suspended state, which is convenient for clamping.

[0036] As the rectangular block moves downwards, the push rods 12 on both sides of the rectangular frame 10 rotate accordingly. As the rectangular frame 10 continues to move downwards, the push rods 12 simultaneously press and push the sliding plates 35. The two sets of sliding plates 35 slide towards both sides of the frame 1. The second racks 41 and the second clamping blocks 36 at both ends of the sliding plates 35 move simultaneously. The sliding plates 35 continue to slide until the second racks 41 mesh with the second gear 40, thereby driving the second gear 40 to rotate at the bottom of the frame 1. The second gear 40 is simultaneously connected to the third rack 42 at the bottom of the frame 1. When the second gear 40 rotates, it drives the sleeve plate 37 to slide at the bottom of the frame 1 through the third rack 42. The sleeve plate 37 slides towards the sliding plate 35 and drives the third clamping block 38 to move simultaneously until it cooperates with the second clamping block 36 to clamp the other part of the roof, thereby enabling the inverter and the frame 1 to be installed quickly and simultaneously.
